Yamnichun

Yamnichun was a Hunkpapa Sioux village in Kansas, established in the mid-18th century. Its name means "Three Trees" in Lakota, and the village was led by Finds Buffalo during its conflict with Spain, whose colony of Fort Perales encroached on Sioux lands. The Yamnichun Sioux proceeded to destroy Fort Perales in 1776, massacring the population and burning it to the ground.
